|

- Open `uip-mcast6.h` and add a section in the `#if` spree. This aims to
|
||||
configure the uIPv6 core. More specifically, you need to:
|
||||
* Specify if you want to put RPL in MOP3 by defining
|
||||
`RPL_CONF_MULTICAST`: 1: MOP 3, 0: non-multicast MOP
|
||||
`RPL_WITH_MULTICAST`: 1: MOP 3, 0: non-multicast MOP
|
||||
* Define your engine details
